Testing of electron beam irradiated sheep wool for adsorption of Cr(III) and Co(II) of higher concentrations

Electron beam irradiated sheep wool dosed (0–410) kGy showing good adsorption properties was tested for Cr(III) and Co(II) of higher concentrations. Fitting to ten isotherm models examined as follows: Langmuir, Freundlich, Dubinin-Radushkevich, Temkin, Flory-Huggins, Halsey, Harkins-Jura, Jovanovic, Elovich Redlich-Peterson. Both cations being Lewis acids generate complex salts, such carboxylates or cysteinates, with ligands from keratin. Various composition architecture the complexes are responsible different model fitting. The chromic cation showed adherence Harkins-Jura Jovanovic all almost samples unlike cobaltous matching Flory-Huggins Redlich-Peterson models. No fitted both simultaneously. On contrary, simultaneously non-fitting observed partially Dubinin-Radushkevich
